PAWCATUCK, CONN. (Aug. 30, 9 a.m. EDT) — Davis-Standard Corp. plans to show its new Euro Blue extruder at K, and will display a new version of its Mesa controller, an extruder for biaxially oriented film, the Culisse winder, a low-profile die for blown film and the WesJet AutoPro air ring, among other technologies.
Booth visitors also can watch a video feed of a running cosmetic tube line at Davis-Standard's factory in Erkrath, Germany.
The Pawcatuck company will detail an extrusion machine that, every minute, slams out 4,000 plastic sticks for cotton swabs.
Davis-Standard will display all four machine sizes of the Euro Blue — extruders with screw diameters of 2, 2½, 3 and 3½ inches. The single-screw machine is designed for custom profile and tubing extrusion, plus basic wire and cable and film applications.
“The Euro Blue is based on the engineering of our widely accepted Super Blue extruder, but has been styled and equipped to meet the requirements of our European customers,” said Gerhard Folie, business manager.
Davis-Standard introduced the Super Blue at NPE 2003 in Chicago, as a lower-cost extruder line. The extruders ship as quickly as two weeks from the order date, the firm said.
Euro Blue features include a sloped front panel with machine access; 400/3/50 voltage requirements; a low-noise, high-torque, double-reduction gearbox; cast-aluminum finned heaters bolted to the barrel; a brushless alternating-current drive and motor; and a high-capacity, efficient air-cooling system.
One Euro Blue line that will be on display is designed to make medical-grade flexible PVC tubing, with internal star-shaped profiles, at a rate of 230 feet per minute.
In other K preview news, the company will:
* Introduce a compact torque motor design, displayed on a high-speed, 3½-inch extruder. The design combines both gearbox and motor functions into a single unit. Design advantages include a hollow shaft, water cooling, fewer mechanical parts and high rigidity. The motor can turn a screw 200-300 revolutions per minute. The motor is especially helpful when processors want to remove the screw from the rear of the extruder without disrupting downstream equipment.
* Exhibit the latest version of its low-profile die coextrusion technology for three-layer blown film, called Lo-Pak. The brand serves a range of applications, including converting film, barrier food packaging and specialty and laminating films. A shear-rate modeling design reduces residence time and wetted surface area compared with other dies, the company said.
* Display the Mesa III controller, introduced earlier this year, for the first time. It is a lower-priced controller for smaller lines that have one or two extruders.
* Show a 190-inch Model 310A automatic flex lip die for cast film. Flexible control comes through 167 thermal expansion, push-pull bolts — each one fitted with thermocouple feedback control.
* A 10-inch extruder with a unique screw design and a heavy-duty gearbox for running thick sheet or high-output film.
* A special line for making cotton swab sticks — basically round, serrated tubes — at high speeds. A Betapack-Betafeed machine pulls the sticks from the 2.4-inch extruder, cuts them to length and packs them in a magazine.
* Show a laboratory line with a 2-inch extruder with a dual-manifold sheet die and a profile die, so customers can run sheet or profiles on the same line.
* Show a line for extruding engineering materials, such as nylon or polyurethane, into industrial profiles for construction, automotive and household products.
The video transmission from Erkrath will show a four-extruder line making five-layer cosmetic sleeves at a rate of 60 feet a minute.
Davis-Standard plans to show the machine Oct. 21, 25, and 26 for two hours daily. Exact times will be posted before the show.
